Reincarnated In Attack On Titan World As Nobody

On the final day of equipment maintenance, Shin finally completed the task.

He felt a rush of satisfaction—but also a faint trace of melancholy.

He was ready to focus entirely on preparing for the upcoming conscription meeting… until the system delivered a new, non-mandatory quest:

[Enter the Hall]

Mission Objective: Forge a high-quality tool using your own abilities.

Mission Reward: Strength +3, Coordination +3, Weapon Mastery +3

Mission Penalty: None

Mission Deadline: Three months

"Why the hell am I being made to compete with a blacksmith now?" Shin muttered in disbelief, rubbing his forehead. "Wait a minute… Is this golden finger trying to turn me into a master craftsman?"

The more he thought about it, the more it made sense—and annoyed him.

If he had time, he wouldn't have minded the challenge. But the conscription meeting was only a month away. With his current skills, forging something that qualified as "high-quality" was a tall order.

Thankfully, the system hadn't specified what kind of tool he had to make. That gave him some wiggle room. A simple iron rod was leagues easier than crafting a flawless blade.

Still, Shin hesitated. Should he really divert time and energy for a bonus stat boost? He had only so many days left to hone himself for what was coming. If he didn't make it into the Training Corps, everything he had built up could crumble.

No matter how strong he became, bare fists wouldn't be enough to fight a Titan. And despite all his growth, Shin was still a long way from being able to rip one apart with his bare hands.

With a deep breath, Shin decided to shelf the forging task for now and focus on more urgent priorities.

Uncle Harry, having already accepted Shin's intent to enlist in the Survey Corps, adjusted his schedule accordingly. After wrapping up work with the Garrison Corps, he told Shin to only come into the forge for half-days. The rest of his time was his own to prepare.

Shin agreed without hesitation.

He'd already outgrown the basic weight training. His attributes—strength, endurance, coordination, and explosiveness—had all risen beyond what the training room could help with.

He wasn't entirely sure where he stood without formal testing, but based on how he felt, Shin guessed that three or four grown men wouldn't be able to restrain him in a fair fight.

In an all-out brawl with no weapons? Ten might be possible.

Compared to most recruits, he was bound to stand out like a crane among chickens.

And that was exactly what he intended to do.

Shin wasn't interested in hiding his strength. On the contrary, he wanted to perform so well that he couldn't be ignored. Exceptional results brought exceptional resources—and protection.

Thanks to his physical foundation, he could now start training with precision. Giants required mobility, gear mastery, and swordsmanship. So even without an official black gold bamboo blade, Shin decided to improvise.

Near the river on the northwest edge of Shiganshina District, a boy could be seen early every morning, swinging two thin bamboo poles with relentless focus. His movements—measured, flowing, and increasingly sharp—cut through the air in fluid arcs.

Passersby stared, then instinctively gave him space. Something about the intensity in his eyes made people uneasy. Some whispered that he was odd. Others thought he might be slow in the head.

Shin ignored them all.

He had no interest in explaining himself. He didn't know these people, and their opinions didn't matter. All that mattered was refining his technique.

As a longtime fan of Roronoa Zoro, Shin had initially tried to imitate the infamous three-sword style.

That… didn't go well.

Even after boosting his bite strength, it was just too ridiculous. The shame he felt every time he tried clenching a bamboo stick in his mouth eventually made him give up.

Two swords it was.

Besides, that was the standard style used by the Survey Corps. No one got special treatment in a real battle.

In the first few days, Shin didn't see much improvement in technique. But strangely, his left and right hands began to move more fluidly, more in sync. His balance was better. His footwork lighter. He didn't question it.

He just kept going.

Over time, his movements grew sharper and more refined. He worked himself into a full sweat, despite the biting cold of January. Dressed in nothing more than a light tunic, Shin barely felt the chill. His body ran hot from the intensity of his training.

Passersby now glanced at him with both curiosity and unease. A kid radiating steam like a human furnace wasn't something you saw every day.

"There are downsides to being too fit," Shin muttered, wiping his brow.

His muscles burned, his heart pounded, and he was drenched in sweat—but he hadn't yet hit his limit.

Still, he powered through, relying on sheer will.

Finally, after a relentless set of movements, the system's sweet chime echoed in his mind:

Ding! The host has completed extreme training.

Grip Strength (both hands) +1. Coordination (left and right hands) +1.

"Hah… hah…"

Panting heavily, Shin grabbed his thermos and took a long sip of hot water. As the warmth spread through his body, he turned and noticed two familiar figures waiting patiently at a distance.

Eren. Mikasa.

"What are you guys doing here?" Shin asked, surprised.

"I knew it," Eren groaned, walking up. "You totally forgot. Again."

Shin blinked.

"Forgot what?"

"Your birthday," Eren said flatly. "It's today, Shin. Everyone's already waiting at your house. Mom, Dad, Uncle Harry. You're the last one."

"Ah… right." Shin scratched the back of his head sheepishly. "I might have forgotten."

Mikasa, silent until now, spoke softly. "We've been waiting a long time, Shin."

"Alright, alright," he said, throwing on his coat with a grin. "Let's go back."

As the three of them walked together, Shin glanced at Eren and smiled faintly.

They shared the same birthday. Coincidence—or fate?

He couldn't help but wonder.

Back on New Year's Eve, they'd all celebrated together. Eren had once again declared that he'd join the Survey Corps when he was old enough—only to be smacked down by both Carla and Grisha in a flurry of familial outrage. Shin had barely held in his laughter.

The future commander of the Rumbling… being pelted with potatoes for being too stubborn as a kid. Life really was strange.

But Shin knew better than anyone—everything was about to change.

The year was 845. The wall would fall soon.

There was no time to waste.

He just hoped that by then, he'd be strong enough to survive what was coming.
